计算图像的灰度共生矩阵，及相关的纹理信息，主要用于图像检索和分类(Calculate the image gray level co-occurrence matrix, and the texture information, mainly for image retrieval and classification)

函数Jf用来求所付代价的增加值，只要在matlab中输入Jf=Jf(a)得到的结果就是J了，其中a的值为对应的 值； 函数Rf用来求所收益增加值，只要在matlab中输入Rf=Rf(a)得到的结果就是R了，其中a的值为对应的 值； 如果要修改表格的值的话，就对应的修改函数Jf和Rf中的数组y的值就好了，M的值和N的值以及r的值都可以修改的。 (The function Jf used to ask to pay the increase in value of the consideration, in matlab enter Jf = Jf (a) the results obtained is J, where the value corresponds to the value of a The function Rf be used to seek the revenue increase in the value of input in matlab Rf = Rf (a) the results obtained is R, where a is the value corresponding to the value of If you want to modify the values ​ ​ of the table, then, the corresponding modified function Jf and Rf value of y in the array like, the values ​ ​ of M and N values, and the value of r can be modified.)

K均值有效执行++多元数据的聚类算法。它已经表明，该算法具有的总群集内距离的期望值是日志（K）的竞争力的上限。此外，K -均值++通常远高于香草收敛K均值少。(An efficient implementation of the k-means++ algorithm for clustering multivariate data. It has been shown that this algorithm has an upper bound for the expected value of the total intra-cluster distance which is log(k) competitive. Additionally, k-means++ usually converges in far fewer than vanilla k-means.)
